BackgroundPatient candidates for breast reconstruction with free deep inferior epigastric perforator flap (DIEP) may present several risk factors for venous thromboembolism (VTE). Risk identification is essential for appropriate VTE prophylaxis measures to be put in place. This study aims to investigate VTE incidence after DIEP flap breast reconstruction and to assess the accuracy of the Caprini Risk Assessment Model (RAM), which is the unique score validated to assess the VTE risk for plastic surgery procedures and identify patients at high VTE risk.MethodsA chart review was conducted of 192 consecutive patients who underwent breast reconstruction with a DIEP flap from 1999 to 2016. VTE rate was assessed and the Caprini score was calculated for each patient and correlated with the VTE incidence.ResultsDuring the 90 post-operative days, four patients presented a pulmonary embolism (2.1%) and two patients (1%) had deep venous thrombosis (overall VTE incidence of 3.1%). Most patients (92.2%) were assessed as high-risk (Caprini score >5) and all VTE occurred among this group. Apart from the Caprini score, no specific single risk factor could be identified for VTE.ConclusionsOur data confirm that the Caprini RAM is a valuable assessment tool for VTE risk measurement among all patients undergoing autologous breast reconstruction. As most candidates for DIEP flap belong to the high-risk group, combined anticoagulation prophylaxis methods are required for most cases, particularly chemoprophylaxis up to four weeks postoperatively.
